| 中文摘要: |
| 本研究提出了用盘式负压入渗仪(Disc infiltrometer)测定的入渗数据计算土壤导水参数的一种新方法。该方法可以用大于10min入渗时间的任何入渗率数据计算土壤导水参数。一种迅速准确的数值迭代法被用于解所得的高度非线形的方程组。新方法所计算的土壤导水参数与实验室测定数据比较吻合，与其他计算方法相比，新方法所得到的导水率与宏观毛管上升高度准确合理。 |
| 英文摘要: |
| A new procedure for calculating the hydraulic conductivity and macroscopic capillary length using the data measured by disc infiltrometers is proposed. A quick and accurate iteration method is applied to solve the resultant highly nonlinear equations. The hydrualic properties calculated from this procedure are compared with those from laboratory measurement and other calculation procedures. It shows that the new procedure gives better estimation of hydraulic conductivity and macroscopic capillary length. |
